-9z + 2 = 11
Z = -1
Find the measure of the interior angle of the triangle.
x + 32 + 48 = 180
X = 100
2x + 3x = 10
x = 2
6x - 3 (x+8) = 9
x = 11
X + 6 = X
Find the measure of the interior angle of the triangle.
x + ( x + 28 ) + 90 = 180
X = 31
x + 1/6 = 4 - 2x
x = 23/18
5(2 - y) + y = -6
y = 4
-2x = x + 15
X = -5
Find the measure of the exterior angle.
x = 36 + 72
X = 108
2(1 - X) = 11
x = -9/2
y = -3x + 2
y = 2
-5x + 1 = 31
X = -6
Find the measure of the exterior angle.
2a = (a - 5) + 80
5x + 2y = 4
y/x = -5/2
4y = x
